Be it-known that we, ALVIN B. Sco'r'r and ORLA 1.

Soon, of -Summitville, county "of Madison, and State ofIndia'na, haveinvented a certain new. and useful Machine for Making Hollow Glassware;and we do hereby declare that 'the following is a full, clear, .and

like parts."

'exact' descriptionthereof, reference being had to the accompanyingdrawings, which l'ike'letter s refer to The object ofthis menses is toprovide means f'o r using a vacunm or suction to elevate the lift-overand suspended glass blank out of a press mold-in amachine for makinghollow glassware and to hold the same in this elevated position untilthe operator isready to take .hold of the lift-over and transfer it tothe blow'mold. Iii-connection with'this'feature-of the inventionthere isa valve-controlled means operable by theplufige're a s for causing andalso 'for'shutti'n'g es the'vaciium or suction so as to render'saidniechanisins ee e-1. z. I 1 1 Heretofore hooks and 'othermechanical means have been employed forg'rasping 'or'engagingthe'lift-over and-"e1evatingthesame. hooks, however lare aresufiiciently-positiye or accurate.

, f troublesome to operate and, are always in the way and 2i i..jThelnature the invsnaeniwm beunderstoodho'm th'accompanying thefollowing descrip'- tionand claims.

u In the Figure- 1' is an elevation of a portionplunger-actuatingmechanism and oneset of molds,

of amachihe for hollow glassware showing the 'the moldftable and some 'other'pa rts being partially .brolren away. and thevarious parts beingin-their unopejiated position at the timeof charging the press mold'with glass. -Fig. 2 is an elevation oi the righthand portion of Fig.1,.showing the parts while the glass blank is beingipressed in the pressmold. Fig. 3

is an elevation of the lower part of the mechanism shown i i-Fig.2 withthe plungerelevated-aud the lift- "over and glass bla'rik lifted out ofthepress mold by the suctionm'eans', the parts beingin their positionjust .prior to the release of the lift-over.

Fig. 4- is a horizontal section on the line 4- 4 of Fig. 3 but on alarger scale; Fig. 5 isa; plan view of the lift-over, the handles beingpartly broken hway. Fig.6 isa verticalsection of the suction head, thelifib-ovefand the glass blank on the line 6'--6 of Fig. 4, said blankbeing partly broken away. Fig. 7 is a vertical section centrally throughthe suction valve mechanism.

In detail 'the"machin e is provided with a central tubular frame 10carrying a mold "table 11 that is revoluble on a stationary plate 12,which is held in position by a collar 13 on the lower part of the frame10. Uponthe table-11 there is mounted a press mold 14, anda-blow-mold'li' the complete machine concentric with the axis of thetable 11. I Upon the press mold. there. is placed a lift-over, shown inFigs. Sand" 6. It consists of two members 16 and 17 pivoted together-bythe pin 18, and each member at its'outer endis provided with a handle19, but the body of each memljcr lfi and 17 is provided with asemicircular' opening surrounded with a lower flange 20 adapted to fitin a corresponding recess in the mouth of the molds and a shoulder 21 onthe upper side-to iurnish'a seat for the shoulder 22 at the upper endsecured on the underside of a disk 37. Said menibersrlfi and 17 of thelift-overhave also a catch 24 'on one member adapted'to engage a pin 25on the other; 'as seen in Fig. 5, ion lockingthe parts together in aclosed position Each part of the-lift-over carries a suction plate 65 onthe upper end of"a' c"e'ntral down- :lower end. And thisarrangement isso madethat the plate 65 will have some v'e'rtical play.

' latter ischarged with glassbya gatherer, and then the plungeris-ac'tuated by throwing the lever to the right from the position 'in'.Fig-"1 to that inFig. 2,

compressed air cylinder 31', for c'es downward the plunlocated; T-helower portion of plunger is.

threaded so as to carry anadjus table collar 33 to which a disk34 issecured. Through this disk guide rods 35 extend that hav anadjustablenut36 on the upper. end of each, and at their lower ends are secured t0 thedisk 3'1. Each guide rod 35 has'a spring 38 wound spirally about itbetween the disks M and 37 that tends to force the disk 37 downwardyieldiugly when the plunger rod is moved downward:

A pair of guide rods 40 pass loosely through the disks34 and 37 and attheir lower ends are secured to a'suction head 41. A collar 42 issecured on each rod 40 in such position that it will serve as a stop'for the upwardly moving plate 37.

nular ring, shown in Fig. 6, the hollow portion forming an annularchamber 45 withsuction openings in the underside adapted to registerwith and be covered and closed by the suction plates on the liit over,so that. when 'air is exhausted from the chamber 45, said plates 65 willbe held sin-tight to theunder'side of the suctilSn head 41' and thuselevate the lift-over when the suc chamber 45 by any suitable meansacting.'-through the tube 47 that is connectedwith the portion 48 of thethere'are several sets of these molds positioned on a line wa'rdlyextending stern 26'. that passes 100 813 thr'ough .a hole oi thelift-over member, and has a disk 27 at the After the'liit-over isplaced'upon the presymold', the l 30 which, with suitable meansl ixrfconnection'witlP the ger-rod 32 on the lower end f which "the plunger23 is .spring 43.

The stem 52 has a head 54 that limits the opening movement of-their highest position prior to the release of the liftovcr. Saidvalve-controlling rod 55 operates loosely in the sleeve 56 secured tothe plate 34, and there is acollar 57 fastened to the rod 5-5 above thesleeve 56 to cause said sleeve 56 to lift the rod 55 ofi of the valvestem in the beginning of the upward movement of the plunger. p l

The liitover will be held pneumatically in the upward position until itis removed hy' the operator. The lift-over isremoved by giving one ofthe handles a slight li teml movement which causes a disk 65 to uncoveran opening or part in one suction chamber 4-5.

Then the inrush-of aifpassing'through the valve casing 49 willautomatically close the valve 51. An arm 58 is secured to the tubularframe 10 for positioning the lift-over and holding it inplace on thepress mold.
